Abstract

The present invention discloses a method of fabricating a composite material hockey stick shaft using internal bladder pressure molding technology. The bladder is inserted over a mandrel and composite materials are disposed on the bladder forming a soft, uncured piece. The mandrel is removed and the piece is disposed in a mold following which air pressure is applied to the bladder which deforms the piece to conform to the shape of the cavity. The addition of pressure and heat cures the composite materials and produces a finished hockey stick shaft.
